1 Succession Trophic Levels Food Webs Biomes

2  Series of predictable changes that occur over time in response to disturbances.  Two types Primary –Occurs on “new” ground (little/no soil)  Glacier melt  Volcanic lava/ash Secondary  Disturbance over existing soil (ex. old farmland)

3  Occurs where no ecosystem was before.  On rocks, cliffs  Soil building occurs

4  Soil particle sizes: how they are classified:

5  Volcano adding new land to Hawaii

6  Lichens begin growing

9  Primary succession can be seen happening on the sidewalks.  If left alone, even NYC would return to a cement filled woodland.

10  Grasses and other species begin to cover in subsequent years

22 Decomposers (bacteria and fungi) Producers (Plants) Primary Consumers (Herbivores – eat plants) Secondary Consumers (Carnivores – eat herbivores) Tertiary Consumers (Carnivores – eat carnivores) Top two also contain Omnivores (Eat plants and animals)

23 How the numbers of these type organisms actually compare to each other.

26 An example of a Food Web Shows how many organisms are interconnected by different paths.

27 Food chains are different from food webs. Chains only show ONE path of energy flow.
